In above-mentioned polymer elements, its thickness, size are not particularly limited, when polymer elements was laminar shape, its integral thickness (thickness of the part that is made of base portion and upper layer) was preferably 10 ~ 2000 μ m, more preferably 20 ~ 1000 μ m.

In the present invention, polymer elements can further heat, the processing such as irradiation of hertzian wave (such as ultraviolet ray etc.), stretch processing, processed compressed.And, to process by these, the shape of the layer of the substance B on substance B, surface, the polymkeric substance of liquid-absorbing, polymer elements integral body, character (physical propertiess such as the chemical property such as solvability and intensity) can change.

In the present invention, because polymer elements has the upper layer of contain material b, therefore, by selecting material b, the polymer elements surface treatment can be become have preferred character.For example, if the inorganic particle of selecting performance electroconductibility in above-mentioned electroconductive polymer, above-mentioned metallic particles, above-mentioned inorganic particle as material b, then can become to have electroconductibility with the surface treatment of polymer elements.In addition, if select above-mentioned tackiness agent as material b, then polymer elements has binder layer on the surface, surface treatment can be become have binding property.And then, if the inorganic particle of selecting to have given play to insulativity in above-mentioned known polymkeric substance (such as acrylic acid polymer, rubber series polymkeric substance, olefin polymer, silicon-type polymkeric substance etc.), the above-mentioned inorganic particle as material b, then can become to have insulativity with the surface treatment of polymer elements.And then, if select coloring matter (non-leuco material) as material b, then can with the surface colour of polymer elements, can give aesthetic property.Further, if select inorganic particle as material b, then sometimes can be in polymer elements surface performance solidified nature.

So, in the present invention, in top layer and the inside of polymer elements, its character is differed widely.

In addition, in the present invention, polymer elements can contact to make with polymer materials A by making specific dispersion liquid, so the integraty of upper layer and base portion is excellent.

For example, when making water as liquid c, can obtain the polymer elements of water-setting gel, because the polymer elements of this water-setting gel is made by polymer materials A is contacted with specific dispersion liquid, therefore, upper layer is excellent with the integraty of the base portion that contains water.In addition, the polymer elements of this water-setting gel differs widely on top layer and inner its character.

Have again, in the present invention, because polymer elements has the base portion that comprises polymkeric substance a and liquid c, therefore can stably contain liquid in components interior.

This polymer elements can have been given play on the surface required character, and can give play to the character (such as except hot, cooling, flexibility etc.) of bringing by contain liquid (especially water) at base portion.

In the present invention, polymer elements can be used as uses such as cushioning material, cooling material, wrapping material.In addition, when making water as liquid c, can obtain to have the polymer elements of hydrogel, this polymer elements can be used as the heat extraction gelatinous material, moisture thin slice uses.
